Looking for the name of a method of wilderness navigation

What's the name of the method of navigation or orienteering in which you sight a landmark in the distance, work your way toward it, and then repeat with another landmark further off?

Orienteering is perhaps the word you are looking for. I am told it means running between various checkpoints whose position is defined with greater or lesser precision, and where the runner is entitled to visit them in the order he pleases. I would, sad to say, have no first-hand experience of this.

I've always heard that called simply landmark navigation.

Wayfinding maybe? Seems like it might be too general and isn't a sport like orienteering.
